To iii whom n may eminem?,

' Be it irneivn that l, Joran-3C. Hartman n citizen ci :the Unitei States, residing-at the city of Chicago, in theI county'of Cook and Stute of Illinois, have inventedv e new and useful 'improvement in Tire-Repair Devices, of which. the following is a'speciieati rihis invention relates to -ip'uii' devices fory automobile and other tires which have an inner tube and en outer protecting casing.

When the outer easing is accidentally cut or torn the air pressure in the inner tube forces Athe material. thereof'into and through the aperture in the casing, and Ja'ruptureof such exposed portion ofthe inner tbe'ipro' hut such cesings are expensive, heavy, ano

of such. buikthet it is necessary to curry them attached to some exterior part or' the machine, where they are inconvenient unil unsightly.

lily invention provides u structure of such :huructer that it may be readily up lied to casiugs which may be torn or cut amil aii'ord u support therefor, that will fully'protect the inner tube, and in turn be Iprotected by the outer casing, that is light and compact und which. while serving us un emergency repair, is also of permanent and substantial character :unl will give good service in coutiuued use.

The principles of lily invention are illustrutefl in the drawings, in Which- Figure l is a perspective View of a repuir iievice constructed 1n accordance with my invention, aportion of the outer layer being broken uwuy to better illustrate the manner iu which the layers ore superposefl. F iV 2 :i cross section of the`same on the line 2---2 of Fig. Lend Fig. 3 represents the suine ap lied to an automobile tire, a por tion of t e latter being broken away.

in preparing my improved device I take u uiunber of ieces of fabric, comprising u fibrous oun ation and a rubber filling. These pieces l, 2, 3. 4, preferably should be cut di'agioneiy of the threads of the fabric y Specioation of Letters atent. u' minimum mea gunner nr, was. semina.

for oni-he bias, end the cenip or the pieces should beso errsngee on other that e 'ifimorm end sient- *e iii be given from the erige ci tie innerun'ci. one 1 to the edge ,of the outer und snil .est one si. The 'sniailest 'niece shoulii ne such'size that it will e' '-er any'cut or teer yton-*bieb e tire niey e ily be sulijectezi. The rubber portion of members should be softened by a Snitch gasoiene, und the whole y ced' upon e crrn represeutin the curvut md epproximete iiumeter or the tires for unich device is exi'lvent, such intended. The whole is then ripeneii or vulor the inner tubo und without permitting it 'to slick or'binil.

When au accident occurs by which the outer lube is cut or i'oru, it is rcrnoveci und the inner tire (ii nwcssury) replaced or repuirexl in the usuul uuinucr. But, insiemi of applying u spare casing or using n .shoe Hirn peil oulsiiie the casing, my device is app ieri us u support uml repair lo the inside of thc injured one The iusiiie portions of such tire adjacent to ilse opening are horoughly cleansed with gusolcuc, which is also applied lo the exterior of my repair device. The rubber cement thereby softened und the shoe is then put in plncc. it will instantly mllicro to the eleuns'el portions of the cnsing mul thc soit cement will cause n smooth und uniform uttuclunent thereto. When replaced it will he found that, in orlinary ceses, the repair will be suiilcient for permancnt'use and .support of the tire. in any case it will iuiiy protesi the inner tune whose pressure is communicated directly to the casm and the in'ured parte of tiefei latter will ge held firmly together untii pen manent repair, if necessary,can be mede.

l claim:

1. As u new article of manufacture, s circ repair device consisting ci e shoe adapted to conform in shupeo a section ci the tire,

the said shoe being formed of a plurality of superposed layers of rubber fabric secured together and gradually increasing in size from the outermost to the innermost layer; and means for securing the shoe to the inner face of an outer tire.

2. A tire repair device comprising a multiplicity of layers of material of dii'erent sizes superimposed upon' each other and secured together so as to form a slanted face, a fabric covering over said face, and a layer of plastic cement throughout said fabric covering to secure the same thereto and to the tire.

3. In a tire repair device a multiplicity of layers of rubber vfabric of different sizes superimposed on each other to form a slanted face', and a fabric covering placed over said face and cemented thereto.

4. In a tire repair device a multiplicity of layers of rubber'fabric of different sizes superimposed on each other, and secured together to form a slanted or stepped face, and a layer of material on said face adapted to even *the inequalities thereof, and an bestoscoating within said device.

In witness whereof, I have hereunto set my hand this 8th day ofDeceniber A. I). 1908, in t -c presence of two subscribing witmesses.
